modldrv 9S "5 Mar 2001" "SunOS 5.11" "Data Structures for Drivers"
NAME
modldrv - linkage structure for loadable drivers
SYNOPSIS
#include <sys/modctl.h>
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
DESCRIPTION
The modldrv structure is used by device drivers to export driver specific information to the kernel.
STRUCTURE MEMBERS
struct mod_ops *drv_modops; char *drv_linkinfo; struct dev_ops *drv_dev_ops;
drv_modops
Must always be initialized to the address of mod_driverops. This member identifies the module as a loadable driver.
drv_linkinfo
Can be any string up to MODMAXNAMELEN characters (including the terminating NULL character), and is used to describe the module and its version number. This is usually the name of the driver and module version information, but can contain other information as well.
drv_dev_ops
Pointer to the driver's dev_ops(9S) structure.
